OK, here is some more detail. I just replicated the issue and timed it with a stopwatch. I tried this on two 2+ Amp chargers - the Anker charger I linked to previously, which is brand new, charges all of my other USB devices great, and outputs 2.4 Amps per port, as well as the Apple *iPad* charger, which is larger than the smaller iPhone charger and outputs 2.1 Amps.
The white charge light stays on for 17 seconds, then goes black for 12 seconds, then repeats indefinitely in this manner - 17 seconds, 12 seconds, exactly. I wouldn't call this "flashing." And yes, I did this with a stopwatch.
My question to you all is...when your Mojo battery is fully topped off, is this the behavior you experience?
Or, is my unit defective?
